It doesn't take much to be told you're "too fat" for a role.
"I cried for 30 minutes, but then you have to let it roll off your shoulders or it could cause a serious eating disorder," she said.
"A lot of people in this industry hear they need to lose weight more times than they should. It does make you stronger, though. Because if you let that affect you, you can't be in this industry — you'd go crazy."
It's not the first time that Benson has spoken out about beauty standards in the entertainment industry.
Last year, she posted a picture of herself wearing zit cream on Instagram to make a statement about Photoshop.
And two years ago, she and costar Troian Bellisario took issue with the editing in a "Pretty Little Liars" poster.
She wrote on Instagram, "Way too much photo shop. We all have flaws. No one looks like this. It's not attractive."
Benson's interview came as "Pretty Little Liars" is set to return on Jan. 12.
The mid-season premiere will jump forward five years from when viewers last saw the show's characters.
Hanna (Benson) has become engaged, Alison (Sasha Pieterse) has married, and there's a whole new mystery after A's identity was revealed.
